To aZZ whom it may concern.-

Be it known that I, CARL HOLLWEG, a subject of the King of Prussia, residing at Barmen,Kingdom of Prussia, (Province of Rhenish Prussia,) Germany, have invented certain new and useful Improvements in Clasping-Buckles, of which the following is a speciiication. l

This invention relates to an improvement in buckles for Suspenders, belts, and the like,

also serviceable as a clamp for the straps or` cords of blinds, shades, and the like; and the invention consists in the novel features pointed out in the following specification and claim and illustrated in the annexed drawings, in which A Figure 1 shows a sectional side elevation of the buckle or clamp closed. Fig. 2 is a view similar to Fig. l, the clamp or buckle being open, or in the releasing position. Fig. 3 is a sectional side elevation of a modification. Fig. 4 is a sectional side elevation of another' modification. Fig. 5 is a front elevation of the clamp or buckle. Fig. 6 is a detail view of the clamping-leaf. Fig. 7 is adetail View of a spring. Fig. 8 is a sectional side elevation of another modification. Fig. 9 is a front elevation of Fig. 8.

The buckle or clamp consists of the frame s, in which is journaled a roller r, having wings and provided with a clamping leaf or arm b and a spring f. The belt g is passed between the winged roller and the upper edge of the clamping leaf or tongue, Fig. 2, and is then pinched or clamped, as seen in Fig. 1, as soon as a pull takes place in the direction of the arrow, Fig. r1, since then the front wing of the roller moves toward the edge of the clamping-leaf and presses the belt firmly onto the latter. In consequence of the action of the pull of the belt on the roller the belt is held tighter the stronger the strain or pull to which it is exposed. The clamping-leaf b forms a two-armed lever and swings or fulcrums on the bearings or studs 0 o. If the lower lever-arm, on which acts the spring f, is pushed back in the direction of the arrow in Fig. 2, the upper lever-arm or clamping-edge moves forward, the winged roller is slightly7 turned, and the hold on the belt is broken, so that the latter can be freely moved back and forth through the buckle as long as the clampingleaf is held in the de scribed position. On releasing the clampingleaf and on the slightest pull upon the belt g the parts at once assume the position. shown in Fig. 1 to securely hold the belt, the clamping-leaf bracing or striking against a stud or brace d. In Figs. 1 and 2 the brace or stud a is formed by bending the rear wall of the buckle-frame. In Fig. 3 a separate rod or piece a is inserted -to form the brace. The roller r may have any suitable number of wings, Fig. 1 showing two Wings, Fig. 3 showing three wings, and Fig. 4 showing four Wings. The number of wings has of course no effect on the manner of operation.

The manipulation of the buckle is extremely simple. To free the belt, it only requires a slight pressure on the lower part of the clamping e leaf. The clamping of the buckle occurs at once automatically as soon as the clamping-leaf and the inserted end of the belt are let go-apeculiarityof the buckle which is of great advantage when applied to Suspenders, belts, and the like. Since the belt is supported along its entire width by the edge of the clamping-leaf, the belt obtains a secure hold. The clamping-edge of the leaf can also be somewhat sharpened. The hold on the belt is heightened by curving or forming the wings of roller fr so that they to a certain degree surround or grasp the belt. The wear of the belt is very slight, as it is not pierced or punctured, as in the case of buckles, where pointed tongues, hooks, or prongs are applied. Instead of aleaf-spring,

as in Fig. 6, a bent steel-wire spring, as shown in Fig. 8, can be applied, such spring being secured with one branch to a claw or fastening on the rear wall of the buckle-housing, the other branch of the spring being similarly secured-to the clamping leaf or tongue.

What I claim as new, and desire to secure by Letters Patent, is

A buckle consisting of a frame, a rotatable roller journaled in the frame and provided with a series of wings, a swinging clamping leaf or arm pivoted intermediate its upper and lower ends to the frame and having its upper end arranged to clamp a belt against the winged roller, a spring acting upon the IOO lower end of the leaf or arm to throw its up- In witness whereof I hereunto set my hand per end into clamping poston `and a brace in presence of two Witnesses. secured to the frame at a pomt above the CARL HOLLVEG.
